4 Claims.

This invention relates to an improved construction of embossing machine especially designed and adapted for use in aiilxing seals to sheets of relatively thin material such as paper, and especially designed and adapted for' use by notary publics and other oflicials having seals.

More particularly, it is an aim of this invention to provide a machine for embossinga design, monogram or indicia, on relatively thin sheets of material, of the rotary type adapted to be manually operated by the turning of a small thumb knob or head.

Still another aim of the invention is to provide an embossing machine of the type described having rollers coacting for impressing a seal, and having means for limiting the turning movement of said rollers in one direction to position fiat portions thereof in opposed relationship for applyng or removing a sheet or sheets to be impressed with the seal; and having means for closing the slot in the casing enclosing the rollers and through which sheets to be impressed with the seal are inserted, so that when the device is not in use it may be carried in a pocket and the rollers and their drive means protected from dirt and the like.

Still another object of the invention. is to provide a rotary impressing seal of durable construction, which may be economically manufactured, and which may be constructed so that it will be light in weight, small and compact enabling it to be easily carried conveniently in a garment pocket.

Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, which illustrates a preferred embodiment thereof, and wherein:

Figure 1 is a longitudinal cen'tral vertical sectional View, partly in elevation of the rotary impression seal,

Figure 2 is an end view in elevation of the same looking toward the end provided with the actuating knob,

Figures 3 and 4 are transverse Sectional views taken substantially along'the planes of the lines 3-3 and 4 4, respectively, of Figure 1 and Figure 5 is a longitudinal horizontal sectional view taken substantially along the plane of the line 5-5 of Figure 1. l

Referring more particularly to the drawing, wherein like reference characters designate like or corresponding parts throughout the different views, III designates generally the machine which includes a casing, designated generally I I, formed of the corresponding sections I2 and a removable end Wall I3. Sections I2 are each provided with a longitudinal, substantially cylindrical bore Il which is closed at one end by the integral wall I5 and at its opposite end by the removable wall I3. Said last 'mentioned end of each of the sections I2 is connected to the end wall I3 by means of a plurality of fastenings I6 which are threaded to engage threaded recesses I'I in the side wall of each of the sections I2. As best seen in Figures 3 and 4, the two sections I2 when thus assembled together by being connected to the end wall I3 form an oval in cross section. The sections I2 are provided with flat opposing faces I9 which are spaced from one another to form a transverse slot 20 therebetween, and these faces are provided with longitudinal openings 2| which communicate with the slot 20 and with the longitudinal bores I4 of the respective sections.

Mounted in the bores I4 are the impressing rolll ers 22 and 23 which are provided at their corresponding ends with restricted shanks 24 which are 'journaled in openings 25 in the end walls I5,

and at their opposite ends with shank portions 26 l having restricted free ends 2l which are journaled in openings 28 in the end wall I3. Rollers 22 and 23 adjacent the ends provided with the shanks 26, are provided with corresponding enmeshed gears 29. The shank portion 26 of the roller 22 is provided with a pinion 30 which is keyed thereto and disposed between its gear 29 and the end wall I3. A shaft 3| has its intermediate portion journaled in an opening 32 in the wall I3 and is provided on its inner end with the pinion 33 which is in mesh with the pinion 39. The opposite, outer end of the shaft 3l is squared to engage a squared opening 34 in a disk 35 which is detachably secured thereto by means of a threaded screw and washer 36 which are secured in a threaded recess 31 in the threaded end of the shaft 3| to position the washer, which is mounted on the screw 36 in engagement with the outer side of the disk 35. As seen in Figure 1, the lperiphery 38 of the disk 35 is serrated or roughened to provide a nger grip to enable the disk 35 to be readily revolved with the lingers for revolving the rollers 22 and 23, in the opposite direction, by means of the meshing pinions 30 and 33 and the meshing ygears 29.

As bestseen in Figure 4, the-'rollers 22 and 23 are each provided with an arcuately shaped or rounded portion 39 and -a fiat portion 40, said portions 39 and III extending substantially the length of each of the rollers. The arcuately shaped portion 39 of roller 22 is provided with a seal 4I, a portion of which is seen in Figure 1, which is raised relatively to said arcuately shaped portion. The corresponding portion of the roller 23 is provided with a similar seal 42 which is recessed or countersunk in the rounded portion of the roller and which is in a reverse position relatively to the seal 4I.

A bar 43, which is triangular shape-in cross section, is shaped to correspond generally to the shape of the slot 20 and which is disposed and detachably held by having its ends positioned in similarly shaped openings 44 `in the end wall I2 for closing or substantially closing the slot 2liv when the machine I Il is not in use.

As best seen in Figure 3, the pinion 34 is provided with an arcuate groove 45 on its side, which is adjacent to the wall I3, and which extends a substantial distance around the shaft 3| so that the ends of the groove 45 are spaced from one another. A stud 46 projects inwardly from the wall I3 and into the groove 45 to form an abutment,

' by engagement with the ends thereof, for limiting the extent of rotation of the disk 35.

The machine, which is especially designed and adapted for use by notaries and other oflicials having an oiiicial seal, is adapted to be carried in a pocket with the member 43 in place, as seen in Figure l, to protect the parts within the casing I I from dirt and other foreign particles that might otherwise enter thecasing II through the slot 20. The intermediate portion off the bar 43 extends slightly beyond the end of the casing Il so that it may be grasped and removed preparatory to using the seal. The 'diameter of the rounded or arcuately shaped portions 39 are each equal to the space between the axes of the two rollers 22 and 23 so that said portions will contact each other when the rollers are revolved. By turning the knob 35 in a clockwise direction, as seen in Figure 2, until the head or stud 45 engages an end of the groove 45 to prevent further rotation thereof, the at surfaces 40 will Ibe disposed in opposed relationship and spaced from one another so that a sheet of paper may be inserted into the slot 20 between the rollers 22 and 23. The disk 35 is then turned in the opposite direction to the full extent of its move-l ment as governed by the stud 46 and groove 45, which is sufficient to allow the rollers 22 and 23 to revolve so that the raised seal 4I will impress the sheet, not shown, into the recessed seal 42 to emboss the seal thereon. Disk 35 is then turned clockwise back to its original position so that the sheet may be removed. As heretofore `mentioned, the turning of the disk 35 in a. clockwise direction will cause the pinion 33, as seen in Figure 3, to likewise turn' in a clockwise direction to turn the pinion and the gears 23 carried by the roller 22 in a counterclockwise direction to thereby rotate the roller 23 in a clockwise direction. When the disk is turned in the opposite direction the rollers 22 and 23 will likewise turn in opposite directions land it is for this reason that the seal 42 is reversed relatively to the seal 4I so that the top parts of the two seals are disposed adjacent to one another,` when in the position, as illustrated in Figure l.

Obviously, other seals, monograms, designs or indicia may be substituted for the seals 4I and 42 on the rounded surfaces 39 as the portions A of the seals 4I and 42, illustrated in Figure 1, are

Various modifications and changes in the conksaid casing, a pinion on one end of said shaft disposed within said casing for meshing with said A rst mentioned pinion, a knob? keyed to the opposite end of said shaft and disposed on the outer side of said casing for turning the shaft. to revolve said rollers, said casing being provided with a slot extending laterally through the center thereof and from one end to adjacent the opposite end of the casing for inserting a sheet into the casing, between the rollers and to be engaged thereby, and an arcuately shaped groove in one side of the pinion, and a pin projecting from the casing, and engaging the groove for limiting the extent of rotation of said rollers and for positioning corresponding portions of the rollers in opposed relationship when said knob is turned to the full extent of its vmovement in one direction.

2. In a rotary impression seal, a casing including corresponding sections each having a closed and an open end and a substantially cylindrical, longitudinal bore, said sections each having an open side communicating with its bore, a plate forming an end wall for closing the open ends of said sections and for mounting them in spacedv apart relationship relatively to each other withtheir open sides in communicating relationship for thereby forming a transverse slot between said sections, a roller mounted in each of said bores and having an end journaled in the end wall of the section and in said plate, actuating means extending from said casing and connected to said rollers for rotating .thein in opposite directions at uniform speed, said rollers each including a l rounded surface provided with corresponding indicia, the indicia of one of said rollers being raised and the indicia of the other roller being recessed and disposed in reverse position relatively to the raised indicia. for receiving said raised indicia when the rollers are revolved, each of said rollers being provided with a ilat surface forming a space between fthe rollers when said surfaces are disposed in opposed relationship and in alignment with the space between the casing sections whereby a sheet may be inserted into or removed from the casing, to be embossed by rotation of the rollers.

3. A rotary impression seal comprising an elongated casing, oblong in cross section, formed of corresponding sections having longitudinal, substantially cylindrical bores, said sections each having a closed and an open end, an end wall detachably secured to the open ends of said sections for closingthe same and for disposing the sections in spaced apart relationship relatively to each other, the adjacent faces of said sections being provided with longitudinal openings com- Amunicating with said bores, a roller rotatably mounted in each of said bores and having one end journaled in the end wall of its section and the opposite end journaled in said removable end wall, said rollers having corresponding meshed gears, one of said rollers being provided with a pinion, a shaft journaled in said removable end wall and provided with a pinion on one end disposed within said casing to mesh with said vrst mentioned pinion, a disk keyed to the opposite end of said shaft and disposed on the outer side of said casing. and forming a thumb knob for rotating said rollers in opposite directions and at uniform speeds, said rollers each including a rounded surface containing a design or indicia, the design or indicia of one of said rollers being raised relatively to its rounded surface and the design or indicia of the other roller being recessed and in reversed position for receiving the raised design or indicia when said rollers are revolved, and said rollers having flattened surfaces disposed ln spaced apart relationship relatively to each other when in opposed positions.

4. A device as in claim 3, said last mentioned pinion being provided with an arcuately shaped groove on one of its sides and extending partially around said shaft, and a stud projecting inwardly from said removable end Wall for engaging said groove for limiting the rotation of the rollers and for positioning said flat surfaces in opposed relationship when said disk is turned to its limit in one direction.
